I'm not saying this to be a jerk. Last time I went to a Payless, every single shoe was uncomfortable and I couldn't buy anything. A woman's shelter probably would've benefited more from a money donation than payless shoes. Juss saying.
From Stephen Mitchell's translation of Tao Te Ching:Chapter 11 We join spokes together in a wheel, but it is the center hole that makes the wagon move. We shape clay into a pot, but it is the emptiness inside that holds whatever we want. We hammer wood for a house, but it is the inner space that makes it livable. We work with being, but non-being is what we use.
